APPARATUS FOR EXTRACTING OIL.

SPECIFICATION forming part of Letters Patent No. 615,104, dated November29, 1898. Application filed May 9, 1898. Serial No- 680,199. (No model.)

To aZZ whom it may concern:

Be it known that I, FANNIE L. POTTERF, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Apparatus forSeparating Oils and Fats from Substances; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form a part of thisspecification.

This invention relates to certain new and useful improvements inapparatus for reducing fats and oils by chemical means, and in carryingout the invention it is my purpose to provide a receptacle in which thesubstance from which the oil is to be separated is placed and acteduponby suitable chemicals, after which the oil may be drawn 01f afterbeing strained by a suitable screen carried within the receptacle;

More specifically theinvention consists of a conical-shaped receptaclewhich is mounted in a suitable standard, said receptacle having a tubingconnected to one side thereof and communicating with the lowerfunnel-shaped end of the receptacle, which latter is provided with asight-aperture protected with glass or mica, whereby the chemical actionmay be watched and the quantity of oil separated determined.

To these ends and to such others as the in: vention may pertain the sameconsists, further, in the novel construction and arrangement of parts,as will be hereinafter more fully described and then specificallydefined in the appended claim.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisapplication, and in which drawings similar letters of reference indicatelike parts throughout both views, in which- Figure l is a perspectiveview of my improved oil-separator/ Fig. 2 is a vertical centralsectional view through the receptacle and attachments.

Reference now being had to the details of the drawings by letter, Adesignates the receptacle in which the substance from which the oil isto be separated is placed. This receptacle is made, preferably, of theshape shown and has its lower end tapering to the outlet B, at whichlocation a stopcock may be located for the purpose of drawing off theoil that has been separated. The upper end of the receptacle has a lidor cover 0, through which the substance is placed in the receptacle. Ata suitable distance from the lower end of the receptacle is disposed ascreen D, through which the oil passes and accumulates in the spacebelow the screen. In the side wall of the oil-receiving portion of thereceptacle is a glass or mica covered aperture F, provided for thepurpose of ascertaining the quantity of oil that has accumulated andalso of noting the chemical action that is taking place within, while asecond and elongated glass-covered sight-aperture E is pro vided in theportion of the receptacle above the screen for the purpose of seeing thequantity of substance from which the oil isbeing extracted.

A support I-I, having a band J, is provided, in which latter the conicalportion of the receptacle rests when in use. This bandJ has an offset Jto receive the tube K, which latter is provided forthe purpose ofpouring in the chemical through the funnel K at the upper end of thereceptacle. The lower end of the tube K communicates with the portion ofthe receptacle beneath the said screen, as shown, and the longitudinalportion of the tubing is fastened to the outer side wall of thereceptacle, as illustrated. Any suitable solvent may be employed,dependent upon the character of the material being treated.

In adjusting the apparatus for use the fatty substance from which it isdesired to have the oil separated is placed in the receptacle and thechemical, of whatever kind, which is used as a solvent is poured intothe filling-tube K and acts upon the fatty substance, and the oil thatis reduced may be drawn off at the lower end of the receptacle, thesight-aperture being provided so that observations may be made from theoutside without taking off the cover.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

The combination with a receptacle having a conical lower portion with ascreen therein, and a filling-tube extending from near the lower end ofthe receptacle below the screen and extending upward alongside theinclined outer wall of the receptacle and parallel therewith and securedto said wall near its upper end and provided with a funnel at its upperend, of a support having a band encircling the receptacle above thelower end of the filling-tube and ofifset to receive and. embrace issaid tube, all substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

FANNIE L. POTTERF.
